I recently (today) had cause to have both front resonators removed from my 86 GTV6 as both were rusted out and holed.
Primarily due to location at the time I elected to use Mettams mufflers on Gt. Eastern Highway, Belmont WA.
They had a full book of work on but moved things around to accommodate me with very short notice and my limited availability.
They not only did the job well and as discussed but also well by the promised time and at the agreed price.
This plug is not in return for free or reduced cost work but simply because it is nice to know genuine operators are still out there, especially that treat our type of marque with respect, not disdain.
Brian the owner tells he does a number of European classics like Fiat (124), Triumph (stag) and now Alfa's (GTV6), not just the Jap boy racer cars.
So, well recommended.
